I was feeling sick to my stomach before day one but decided to try it anyway. Bad idea. I felt like I was going to die after 10 minutes and struggled through two more rounds before stopping the clock at 15:30.

I sacrificed my form too much on the pullups, though. If I had broken the 5-minute mark it wouldn't have felt right to move up.

L5D1: 24 Rounds
Change: +7

Here I kept good form. I paced myself better and that helped me perform more consistently throughout the 20 minutes. Before, I was getting wiped out by the 15 minute mark and completing almost no rounds after that.

On paper the jump from level 5 to level 6 doesn't look so bad. Day 3 has 6 extra pull-ups, 13 extra push-ups, and 13 extra squats. I was already running up against my limit for endurance on L5D3, however, and getting those extra pull-ups and push-ups was really tough to do. Even the squats had me taking breaks.
